Perhaps you should try some spelling variations:
decrease yield » decreases yield (Expand search), increase yield (Expand search), increases yield (Expand search)
decreased rate » increased rate (Expand search), decreased base (Expand search), decreased native (Expand search)
rate decrease » rats decreases (Expand search), rate increase (Expand search), to decrease (Expand search)
yield pattern » yield after (Expand search), yield water (Expand search), yield protein (Expand search)
decrease not » decrease of (Expand search), decrease akt (Expand search), decrease at (Expand search)
not decrease » to decrease (Expand search), not increase (Expand search), and decrease (Expand search)
decrease toc » decrease of (Expand search), decrease the (Expand search), decreased to (Expand search)
toc decrease » to decrease (Expand search), the decrease (Expand search), of decrease (Expand search)

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( decreased rate decrease NOT decrease ) OR ( decrease toc decrease yield pattern ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decreased rate decrease not decrease ) OR ( decrease toc decrease yield pattern ))~".
• Adding a wildcard symbol may retrieve word variants: (( decreased rate decrease not decrease ) OR ( decrease toc decrease yield pattern ))*.
